Specification of Letters Patent.

Application filed April 9, 191 8. Seria1;No.759,845.

To all whom it may concern p Be it known that I, WILLIAM -S. A. Wmnnn, a citizen of the United. States, rcsidin at Anderson, in the county of Shasta and tate of California, have invented new and useful Im rovemen'ts in Devices for Bemoving and eplacing Railroad-Ties, of

i which the following is a specification.

This invention relates to a railroad-tie removin and replacin device. 7

The 0 ject of this invention is to provide a simple and easily operated device by which the old ties of a railroad track may be easily removed and replaced by new ties, without disturbing or removing the surrounding road-bed. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described. and.

claimed, having reference to the accompanyingdrawings, in which- Fi re 1 is a central section of the-device, showing its position upon the rails. Fig. 2 is a cross section on the line X-X of Fig. 1. Fig. 3 is a detail view of the ratchet mechanism. Fig. 4 is a perspective view of the plow member. Fig. 5 is an end view of a track, showing the application of the invention.

Referring to the drawings: A indicates.

in particular the road-bed upon which is placed the usual form of ties 2 and rails a longitudinal bar 8, upon the si es of which are formed rack-teeth 9 and 10, adapted to be actuated by a pair of pawls 11' and. 12,

pivotally mounted as at 13 and 14 in a lever 15 pivotally mounted as at 16 between the si e plates 4 and adapted to be rocked by the application of handles 17, which are se cured in pocket members 18 formed on the lever 15. The lever may be rocked through the handle 17 by manual labor, and Wlll when rocked about the pivot 16 transmit reciprocal movement to the pawls 11 and 12, which movement in turn will be transwith the mitted through the ratchet'teeth'Q and 10 Patented Nov. 1 1, 1913.

to force .the longitudinal bar 8 in'the di- :rection of arrow (1. One end. of the bar 8- is provided with an upwardly turned hook member 19, which becomes engageable with a spring-actuated catch pawl. 20, pivotally mounted as at 21 between the plates.

The hook 19 and the catch pawl 20 are provided for the pur ose of limitin the outward movement 0 the bar 8; or in other words, to prevent its complete removal from the plates. The opposite end of the bar 8 is provided with adownwardly dprojectingj aw 22, which extends downwar a sufiiqient distance to en age with the on of the'tie 2, I

upon which t e rails 3 are mounted.

In order to secure the ratcbetjack here shown upon the rails when it is placed in position with relation to a tie, It is accomplished by'formin suitable depressions 6 in the lower edges 0 the plates, which are adapted to straddle the tracks, as shown in Figs; 1 and 5.

In operation when it is desired to remove the tie 2, indicated in Fig. 1-, it is' accomplished by placing the ratchet jack upon the tracks in such position as to cause the depre ions 6 to grip the rails 3. The lever 15 is ihen rocked by the handle 17 until the downwardly pro ecting jaw 22 engages lid of the tie 2; A continued rocking movement of the lever 15 will thus cause the bar 8 and Jaw 22- to move in the direction of arrow a and force the tie outwardin the direction of the .arrow to the dotted line osition indicated atv 23. The positionoftiie 'raillimits any further movement ofthe bar and' paw 22, as at this point engagement is made with the supporting rail. It then becomes necessary to return the ratchet bar 8 to its extreme outward position, indicated in Fig. 5. In orderto return the ratchet bar 8 to this position, it becomes necessaryto elevate the pawls 11 and 12 out of engagement with the ratchet teeth 9 and 10 formed on the sides of the bar 8. This is accomplished by providing 5 the pivot member 13 of the pawl 11 with. a

lever 24, which is turned upward in'the direction of arrow 12, shown in Fig. 3, inwhich position the end of the lever 24 is retained by a latch or hook 25. The movement of the lever from its normal position, indicated in Fig.3, to the elevated position assumed when brought into enga ement with the latch 25, is transmitted t ough the moved to its extreme outer position, indicated in Fig. 5, is then returned by rocking the lever through the medium of the handle 17. A' new tie, as indicated at- 26,'hav1ng1 been interposed between the old tie 2 and than that occupied by anew tie.

' to be forced out of the path, this being pro ected upward through the curved pockets the jaw 22, the movement of the bar '8 and jaw 22 will thus be transmitted through the new tie 26 to force the old tie 2 out from under the track and force the new tie 26 into the position formerly occupied by the old tie.

In some instances it often happens'that' the old tie becomes so deteriorated that the space'occupied by same is considerably less It thus becomes necessary to remove a film of earth of suflicient thickness to make place for the new tie, whichisto be inserted beneath the rails 3. This is accomplished by interposing a plow member 27, indicated in Fig. 4, between the old tie and the new tie. The plow member is provided with serrations or teeth 28 which engage the surroundin material which is forced upward throu the curved channels 29 formed on each side of the plow as the tie isadvanced into position. The forward portion of the plow is provided with a contact plate 30, which engages with the rear portion of the old tie ,to force this out of position, while the rear of the plow is provided with a shoe 31 and asharp projection 32 which becomes thoroughly embedded in the forward portion of the new tie. This means bein provided for the purpose' of securing t e plow in perfect alinement and preventing its accidental removal fromthe forward portion of the tie 26, or from engagement with the old tie 2 which is bein forced out of position by the pressure of t e bar 8, which is transmitted through the jaw 22 and tie 26. The forward face of the plow is'of exactly the same area was the cross areaof the tie, and will thus cause the accumulation of road-bed material 29 formed on the forward portion of the plow.

The device here shown is simple and compact in construction and may be easily oper- 1 plow. attachment shown, it 1s possib e to.

ated by unskilled labor. By providm the remove the necessary quantity of material during the operation of replacing the tie.

The materials and finish of the several parts of the ratchet jack are such as experience and-judgment of the manufacturer may dictate.

Having thus described my invention,

what I claim and desire to secure by Letters Patent is: j

. 1. The combination in a railroad tie removing and replacing device of a pair of interspacedplate members secured with re-. lation to each other, a bar slidably mounted interspaced late members secured with re-' lation to eac other, guide rollers journaled in said plates; a ratchet bar mounted between saidr'ollers, a downwardly projecting jaw formed on the end of the bar adapt-' ed to en age with the end of a tie, means formoving the. ratchet bar between the rollers, means forpreventin the complete removal of the ratchet bar rom the platesand rollers, and means for securing the plate members .on the rails of the track.
